These are the 4 clinical studies that prove that penis extenders work. If you have been looking for Sizegenetics Clinical Trial findings or Clinical studies (peer reviewed) you can find the 4 of them below.
What is a penis extender?
A penis extender is a penis enlargement device that is just like a workout device though it is easy to use and you don’t have to do any work. It is designed to stretch your penis and is scientifically proven by several clinical studies to work.
Below we will learn more about penis extenders along with Clinical studies and doctor recommendations done on them.
Penis extenders claim to offer a wide range of benefits including:
- More girth
- Greater length of the shaft
- Better erections
- Curvature Correction
We wish we could have some strong evidence right?
This is where Sizegenetics shows up to help us. Reviews have shown Sizegenetics to provide best results. It is also rated as most comfortable penis extender that was invented by a team of UK based Urologists. We will talk more about it, but let’s talk about the clinical studies / trials first.
The internet is full of reviews from users who claim to have increased their girth, length and got a better erection and reduced the curvature.
Which Clinical Studies Back Up These Claims?
Yes, there are at-least 4 real clinical studies that do. We will talk about each of them.
Penis extenders have been demonstrated in laboratory conditions to result in increasing of length, girth, greater erection and curvature correction.
- Clinical Study Published in British Journal Of Urology Proved That Penis Extenders Work
The clinical study was titled “A pilot phase-II prospective study to test the ‘efficacy’ and tolerability of a penile-extender device in the treatment of ‘short penis’”
The study was conducted by Giovanni Pappagallo, Alessandro Tizzani, Nicola Mondaini, Paolo Gontero, Massimiliano Di Marco, Gianluca Giubilei and Riccardo Bartoletti at San Giovanni Battista Hospital at the University of Turin, Italy.
As per the study, the patients wrote the penis extender for 4 hours per day for 6 months. After 6 months, the mean gain in penis length was 2.3 and 1.7 cm for flaccid and stretched penis respectively.
The erectile function (EF) improved “significantly” as well.
The increase for penis girth was “little to none”.
So, how much increase could you possibly get?
18% increase in flaccid length
32% increase in stretched length
Our expert views: These findings of the study are significant. If a penis extender is worn for 6 hours a day for 6 – 12 months, the increase in penis length and erections can be significant while the increase in girth can be good and the curvature can be corrected significantly.
Among all extenders available on the market, Sizegenetics is rated as most comfortable and effective by user reviews online. It has also been featured in GQ magazine.
2) Clinical Study That Proved Penis Extender Works For Reducing Curvature Published In Journal Of Sexual Medicine
Peyronie’s disease causes curvature of the penis resulting in pain or problems with erection at times. Peyronie’s disease occurs due to scar tissue developed along the penis which results in plaque which can cause the penis to bend or have difficulty with erection.
This clinical study has demonstrated the use of penis extender to help with Peyronie’s disease.
Fifteen patients with a curvature less than 50 degrees with little or no erectile dysfunction were eligible for the study. They used the penis extender for at least 5 hours per day for a period of six months.
As a result, the average curvature decreased from 31 to 27 degrees over six months. The penis length (stretched and flaccid) increased by 1.3 and 0.83 cm.
It was concluded that a penile extender device can reduce curvature with lasting results and can lead to significant penis length increase (both flaccid and erect). It should be noted that patients selected for the study had little to no erectile dysfunction problem.
This study by International Society For Sexual Medicine was published in the Journal of Sexual Medicine Volume 6, Issue 2, pages 558–566, February 2009
- Clinical Study by Canadian Journal Of Phalloplasty With X4 Labs To Study Effect of Penile Extenders
This study was conducted by an independent medical journal called the Canadian Journal of Phalloplasty in conjunction with X4 Labs to study the effectiveness of a penile extender for penis length increasing.
21 patients took part in the study out of which 16 were able to achieve successful results. The results were stable after the usage was discontinued. This study proved yet again that penis extender can help with penis enlargement and that it is an effective alternative to cosmetic or plastic surgery.
The patients used the traction device for a period of 5 months for 6 to 8 hours per day. They used 500 to 2000g of tension in the device. Dr Frank Clementine, the lead researcher, concluded that 16 out of 21 patients were able to get successful results with 32% increase in length and 36% increase in girth. The results were seen in both erect and flaccid lengths. Erectile strength also increased by 36%. Dr Clementine also reported correction in curvature for the 16 patients.
This study proves that penis extenders are a natural way of penile enlargement, erectile improvement and fixing curvature harmlessly with lasting results as compared to expensive and often risky cosmetic surgery.
- Penile Elongation Using Stretching – Scandinavian Clinical Study
This study was titled Non Surgical Penile Elongation using Tissue Extension – Tractive Elongation of the Penis by Means of Stretching and was presented at 1st International Interdiscliplinary symposium on Genitourinary Reconstructive Surgery in Congenital Malformations, Transsexuals and Impotence at Sitges (Barcelona, Spain) on April 6, 7 and 8th, 1998 by the study author Jørn Ege Siana, MD of Scandinavian Clinic of Plastic Surgery in Copenhagen, Denmark.
The traction device used was a basic ring with two adjustable weights. A force of 600 to 1500 g was attached to the penis.
10 patients took part in the study. They used the device for 12 hours a day for 8 to 26 weeks.
According to the study, there was an average 28% increase in the penis length. All patients successfully increased their penis size, an average of 28%. An average of 1 – 2 mm of increase was witnessed per week. No complications were reported.
Four Clinical Studies Prove That Penis Extenders, when used for about 6 hours a day for 6 months are almost sure to result in penis enlargement. So there is really no reason to not try a penis extender especially when high quality extenders such as Sizegenetics have a 6 months money back guarantee (tested by us)
